Here's a link to a new calculation spreadsheet that incorporates the star/sun almanac to find GHA and LHA for Longitude calculations.

No need to use the Online Nautical Almanac to look up tables.

So far, looks like the spreadsheet only works in Excel, I couldn't get it to work in Google Sheets.
I haven't tried it in any other spreadsheet programs.
